I don't think Chalabi was a tool of the people behind the war so much as it was two groups using each other.

The PNAC people needed a publicly acceptable reason to invade Iraq. Chalabi has been trying to get anybody to overthrow Saddam for him, including Bush Sr and Clinton. Chalabi feeding the PNAC group at the Pentagon bogus / exaggerated intelligence was simply a marriage of convenience.

Still, the US might hang Chalabi out to dry if we need to. If, by some chance, it gets to the point where we need to prosecute somebody, Chalabi is the obvious target.
